I just saw this sign yesterday and was thinking how many ways it could be parsed:

"Big golf factory sale opening"

Seems like at least 8:

"Big (golf factory)" vs "(Big golf) factory"

"(factory sale) opening" vs. "factory (sale opening)"

"... opening:V(PresentProgressive)" vs "... opening:N"

Only two of which are semantically likely, and one of which is pragmatically likely - unless you're really rich and in the market for golf factories.
